Large-Scale Distribution of Arrival Directions of Cosmic Rays Detected at the Pierre Auger Observatory and the Telescope Array above 10[sup]19 eV

Abstract: The large-scale distribution of arrival directions of high-energy cosmic rays is a key observable in attempts to understanding their origin. The dipole and quadrupole moments are of special interest in revealing potential anisotropies. An unambiguous measurement of these moments as well as of the full set of spherical harmonic coefficients requires full-sky coverage. This can be achieved by combining data from observatories located in both the northern and southern hemispheres. To this end, a joint analysis using data recorded at the Pierre Auger Observatory and the Telescope Array above 10[sup]19 eV has been performed. Thanks to the full-sky coverage, the measurement of the dipole moment reported in this study does not rely on any assumption on the underlying flux of cosmic rays. As well, the resolution on the quadrupole and higher order moments is the best ever obtained. The resulting multipolar expansion of the flux of cosmic rays allows a series of anisotropy searches to be performed, and in particular to report on the first angular power spectrum of cosmic rays. This allows a comprehensive description of the angular distribution of cosmic rays above 10[sup]19 eV.

Paranoia in Images : Fears through the Photographic Medium
Roberta Battiston, 2015, undergraduate thesis

Abstract: “Strah” je resnični problem z resnično rešitvijo, medtem ko je “paranoja” nekaj kar je nezavedno ustvarjeno v naših mislih in jih lahko tako popolnoma prevzame, je t.i. “naprava moči”, kot v svoji teoriji navaja Michel Foucault. Na področju umetnosti, se je s tem fenomenom ukvarjalo že mnogo umetnikov, med katerimi so umetniško gibanje Preraphaelites, Vincent Van Gogh, ekspresionizem z Edvardom Munchem, Jamesom Ensorjem, Emilom Noldom, Egonom Schielom in Oskarjem Kokoshko, prav tako pa tudi surrealizem z slikarji kot so Salvador Dali, Renè Magritte in Max Ernst, so razsikovali področja sanj in domišljije. V fotografiji so pričeli raziskovati notranji svet človeškega bitja, najprej skozi piktorialistično gibanje nato pa še čez surrealizem v katerem so se umetniki kot Man Ray, André Kertész, Hans Bellmer, Philippe Halsman pričeli z eksperimentirati z novimi tehnikami. Lewis Carroll se je vdano posvetil fotografiranju mlade deklice nekje v sredini 19. stoletja. Temo otroštva je raziskovala tudi Loretta Lux. Med neosurrealističnime fotografe lahko spadajo Jerry Uelsmann, Robert in Shana Parke Harrison, Scarlota Ban, Brooke Shaden, Meggie Taylor, Robert Kusterle, Maurizio Frullani, Serigo Culoto, Sergio Scabar, Ingalisa Maria Fina, Enzo Tedeschi, Lorella Klun, Jennifer B Thoreson (Hudson) in Joel Peter Witkin. Jaques Rancière in Roland Barthes na z svojimi teorijami podajata ključ za branje slik v ne-seriji “Tempus Fugit, paranoia manent”. V svoji raziskavi sem želela raziskati zgodovinski razvoj povezave med umetniki in paranojo v namen razumevanja kako se je aktualna tema razvijala skozi leta in jo uporabiti kot začetno točko na poti do ustvarjanja svojega vizualnega jezika.
